This Run is to obtain time-resolved Pa-Beta spectroscopy in IP Peg
(dwarf nova).  The period of this source is 4 hours, which explains
the OB length.  The source undergoes marked brightness increases (from
18 to 12 in V, 13.6 to 12.5 at J) every ~80 days (lasting for ~10 days).  
Please do not observe during these brightness increases.  See the
README file for details as to how to determine whether a burst is
happening.  OB coordinates are for IP Peg.  See README file for slit
positioning information.

No special calibrations required.
